When watching videos, audio gets out of sync...

Whenever I watch any type of video with Firefox, the audio and video do not sync. They are fine if I watch them in IE but I hate using IE (so very slow). I have tried updating firefox, but I have the most recent update. I have updated Java and Adobe as well and none of these seem to be the problem. It doesn't matter which website I use, all videos do this when viewed with Firefox.
== This happened ==
Every time Firefox opened
== ever since I've had firefox but it seems worse lately

I have unchecked the "enable hardware acceleration" and it still will not sync streaming videos properly.

Slideshow audio gets out of sync when exported to iDvd

I made a large slideshow for a 40th anniversary party. It has 244 images & 7 songs. It is 29 min 54 seconds long. When I view the slideshow in iPhoto it works fine & the last image ends right at the end of the last song.
When I exported it to iDvd, the audio gets out of sync with the video. By the end of the first song, the video is about 2 seconds ahead. By the end of the last image, the last song is cut of by about 30 to 45 seconds. I tried exporting the slideshow directly to iDvd. I also exported it as a large movie & it did the same thing.
I'm using a 17" 1.67ghz powerbook with 1.5 gigs of ram.
I'm using OS 10.4.2.
I'm using iPhoto 5.0.4
I'm using iDvd 5.0.1
The images are scanned tiffs. I also have jpegs that I shot with my canon eos digital rebel xt.
Anybody have any ideas or work-arounds?

I suggest you either use iDVD to create two slideshows or use iMovie to get all 277 images and the 8 audio tracks into one slideshow. If you use iMovie after you get the slideshow/movie put together and completed quit iMovie. Then go into the iMovie project package (Control-click and select Show Package Contents). The find your movie in the Shared Movies folder and drag it into an open iDVD menu. This allows iDVD to to the rendering of the stills and give you a sharper image. That movie file you're dragging is a reference movie so leave it where it is and just drag it into iDVD's window.
If you can live with two separate slideshow (consider it a potty break between the two) and you don't have or need the Ken Burns effect, you can get excellent results by building the slideshows with iDVD from imported stills. The sync to audio in this method works as advertised. I like to add a blank slide at the end of the slideshow so the music fades out during a blank, black slide.

Tape archive DV tape: the audio gets out of sync.

I have some trouble with FCPX working with my DV tapes and camera (via FW).
When importing a .dv file previously imported with iMovie FCPX crashes. When I convert the file to prores with mpegstreamclip it will import but with incorrect date info.
Now I have made a Tape Archive from within FCPX and I can import from there, but the audio gets out of sync at the end of the tape.
Any suggestions?

ITunes 10.5 video and audio getting out of sync

Hi,
my iTunes videos (bought from the store) are getting video and outio out of sync.
I found some hints to turn options in QT but iTunes 10.5 doesn't use QT - isnt'it?
Any ideas to solve this problem are welcome.
Yours Rüdiger

Hi and welcome to the forum!
First of all, don't convert the file to a MP4. What exactly are the specifications of the MPEG file you are using? It would help to know the frame size, frame rate, and the audio rate.
You most likely placed a 32kHz clip in a 48kHz sequence or vice versa.

My audio gets out of sync with my video after capturing from Sony XDCAM

Everything was fine. I captured content from my Sony XDCAM, created pieces, no problem. Imported a .mov from my older FCP (5.1.4). FCP told me I needed to change my settings in order to use the .mov with my current timeline. I said OK, fine. Now, when I capture from my XDCAM some of the audio is in sync but it goes out fairly quickly. Any Ideas? I noticed in the bin the clips which are out of sync have a different data rate then the good ones. HELP!

Final cut pro - editing music video audio falls out of sync

filmed with canon 7D- i play the music in the background for th artist to perform. upon loading up the footage into final cut, i sync the start of the video audio with the record, as they both play it falls out of sync. i did not have this problem when i edited with premiere. any ideas

Sync issues are *usually* going to be mismatched sample rates, for instance, you imported 44.1kHz audio into a 48kHz project.
This happened to me awhile back, and unfortunately, I don't remember exactly what I did to fix it. But what I *think* I did was click on the imported audio and went to the Retime menu and selected Conform Speed. If that doesn't work, right click on the audio in the event browser and select Transcode (if there's an option to do so in the dialog).
It is also possible to manually resync audio by Retiming it. Turn on snapping (N), select the clip, type Command-R and drag the audio clip's retiming handle until the end of the audio snaps with the end of the video clip (this is actually amazingly accurate.) [If your recorded audio is not the same length of the audio on the video, then set markers on the video and audio tracks and retime until the markers snap.] You should do this before any other edits.

Itunes video -- audio is out of sync

I've downloaded three "The Office" episodes over the past two months.
When I first downloaded an episoded it played back fine.
The most recent episode, I noticed the audio gets ahead of the video.
I played back the first episode I downloaded and the video-audio sync is off on that, as well.
Any suggestions?
I have the latest Itunes and quicktime running on my pc.

As you're running the current versions of QT/iTunes
contact iTMS CS:

Thanks
Yeah. I saw that QT wasn't up to date so I installed the new version and it didn't help.

Video and Audio getting out of sync?!

So I have Final Cut Express on my Macbook with 2.4 GHz, 2.6 GB RAM and I am running Mac OSX 10.5.8. I have a 30 minute mpg, which does not import into FCE, so I converted it to an MP4 via a converter. When I play the video in a standalone player (the mp4) everything is fine but as soon as I put it into FCE and render it, the audio starts to get ahead of the video as the video goes on. its fine in the beginning then by the time its 15 minutes in its a good 1/2- 1 second ahead, and gets even worse by the end. CAN ANYONE HELP?!

Audio gets out of sync after export and burn to iDVD - works in iMovie

I've burned my DVD show twice on iMovie and iDVD and the audio music tracks slowly get displaced over the course of the show (15 min) after exporting and burning to iDVD. It gets pushed back so that it starts later each new track...I've locked the audio to the playhead for each new audio track - however, there are some empty gaps between the tracks, does this have anything to do with the displacement? Or should it not matter since the tracks are locked?
I had it all synced up in the playback on iMovie and had it aligned with visuals, however, after burning, it gets displaced and everything gets off...
Any help would be appreciated, thank you
Chris

The problem:

(Scroll down about two thirds to "What's the difference between locked and unlocked audio?" )
The solution:
Always use 16-bit/48kHz audio.

My MPEG video/audio goes out of sync

Hi
I am importing some MPEG- 2 video clips into Premiere Pro. They are totally in sync before I import them but once in Prmeiere the video and audio are no longer in sync. The format is MPEG-2 video, 1920 x 1080,25fps, 48000hz.
Can anyone suggest anything?
Thanks
Miranda

Hi there
Thanks very much, I donwloaded the MediaInfo software.
So the clips came from a Sony NXCam using a Black Magic stem and VMix to record with.
The files are MPEG2 1920 x 1080 as you can see in the screenshot.
The file info in Premiere says they are pixel aspect ratio 1.0
As for codec information, where can I find this?
Regards
Miranda

How do I stop my video & audio going out of sync after adding a still.

Audio/Video Settings - Sequence Preset HDV - 1080i50, Capture HDV, Device preset SonyHDV 1080i50 Firewire, Vid playback Digital Cinema Desktop Preview-Main, Audio Default.
Easy Setup - Format HD, Rate 25.00fps, Use HDV.
Sequence Settings - Gen. Tab Frame Size 1440 x 1080, Aspect Ratio HD (1440x1080) (16:9), Pixel Aspect Ratio HD (1440x1080), Anamorphic unchecked, Field Dom. Upper(odd), Editing Timebase 25, Quicktime settings HDV 1080i50, Quality 100%, Audio Settings Rate 48kHz, DEpth 16 bit, Config Channel Grouped.
I have not tried reloading FCS.

Hold your horses everyone, I've done it ,Yippee!!
It's all down to Percy, that is perseverance, I do not like to give up.
Under Sequence in the Menu bar I clicked on Sequence Settings. There under Render there is a Render Control tab. I changed the codec from 'Same as Sequence Codec' to 'Apple ProRes 422 [HDV, XDCAM HD/EX/HD422 only]' and everything is back to normal, even the pixelating text (see an earlier post of mine). The rendering is quick as well. The world is my oyster.

N8 Video editor.. out of sync audio

Every time i try and join 2 or more videos taken with my N8 using the video editor, the audio gets out of sync after the first video.
Has anyone else notice this?

I'm really shocked that this issue hasn't been resolved with the Belle Update. They've made some good changes to the video editor, now allowing you to save a project before you're finished, etc. However, I can't understand how they haven't spotted and resolved this problem by now. Anyone from Nokia care to respond? This really does ruin an otherwise very promising piece of software!

Video - dialog goes out of sync with video

When I play Movies or T.V. shows on my iTouch the dialog (or audio) gets out of sync with the video. It starts happening after about 5 minutes of play. I close out of the video, re-open it and it's back in sync again for about another 5 minutes.
I had a second generation iTouch and have just purchased a 3rd gen iTouch and it does it on both. It happens on every movie or t.v. show I watch.
Any suggestions?

I really appreciate your help. I tried it with the link you provided and it appears it's the wrong format type. The one I'm trying to convert is a .wmv file. I think that link was mainly for mpegs.
I did successfully convert a 3rd movie .wmv file using videora, so I have to think the problem lies with this one movie clip. What could it be? It plays fine on my computer! The video itself is fine after the conversion too, it's just moving too fast as if in fast forward mode. Then when the video ends (before the music, cuz it's not in sync), the video keeps backing up and continuing from later and later previous spots until the song ends.
If you're out of ideas, I guess I'll try to see if I can find the video somewhere else and download it again (I got this video free from a website). It's super cool.. An F-18 pilot video tapes himself performing aerial maneuvers to the song "magic carpet ride". Darn, I REALLY want that on my ipod!!

CS3 is making my m2t files audio go out of sync upon import

I am using a Matrox Axio LE running Premiere Pro CS3.
I'm using a Focus enhancements DR-HD100 to record in 720p 59.94 in m2t file format. After importing the clips into CS3 the video and audio is sometimes out of sync by 7-12 frames. It seems to happen with varied lengths of projects and there is no way to tell exactly when the video will go out of sync with the video.
After speaking with Techs at Focus I have run a couple tests and I don't think that anything is wrong with my DR-HD100s. I can play the same m2t clips that are out of sync in Premiere Pro CS3 in Power DVD and they play back fine. No issues with sync. It appears that Premiere Pro is doing something with the clips upon import that is messing with the sync.
Any Ideas?

Here are a couple of thoughts:
1.) can you disconnect the Matrox and test the files in a non-Matrox Project? Any better?
2.) as PrPro can have issues with MPEG files, can you Export as a DV-AVI (or similar) from your DR-HD100? Any better?
3.) can you demux your files into elemental streams and Import these separately?
4.) is your OOS issue constant, over the course of a Clip, or does it drift? Constant can be easily fixed in PrPro, by turning Snap OFF, then Alt-clicking the Audio only, and nudging it along the Timeline. Once done, the Audio and Video will be re-linked. Rember to turn Snap back ON. If it drifts, you may need to Razor the Clips and work on the resulting parts separately, as stated before.
5.) have you tried Render/Replace for the Audio? This will get you a WAV file. Is that any better?
Good luck,
Hunt

HELP! Audio goes out of sync after export!

OK, folks. I need your help. I have a looming deadline of THIS FRIDAY to hand this in.
I have a finished multicam edit of a show that runs 1 hr 20 min. It plays back perfectly in the timeline, all video and audio perfectly in sync. Looks and sounds exactly like what I need.
When I export the video as an H.264 file, the audio gets out of sync with the video by 13 frames! But that's not all... It doesn't happen to the entire audio track. There's about 50 minutes in the middle of the video where the audio goes out of sync. The audio at the beginning and ending of the video is lined up perfectly in sync. It's just the middle section that gets screwy.
What do I do?!
This has never happened before, and I've worked a lot with multicam in Premiere Pro CC before this. Never been an issue. I tried uninstalling and reinstalling Premiere, and also deleting all media cache files, but still no dice. I also tried copying the clips into a new sequence in the same project, copying the clips into a new sequence in a NEW project, nesting the sequence... nothing works.
My setup:
MacBook Pro Retina (Rev. A)
Premiere Pro CC (latest version)
Panasonic GH3 footage in 1080p 24p AVCHD timeline
3 cameras & 1 audio WAV file in Multicam
Any help would be greatly appreciated!

OK, I figured out how to fix it:
In Premiere Pro CC, click on SEQUENCE > DELETE RENDER FILES.
Try exporting the movie again.
It worked! I exported the same sequence, and it took a long while to re-render the audio files, but when it was finished exporting the audio and video were in perfect sync. I'm not sure what caused it, but this fixed it, so hopefully anyone else having this issue can save a lot of time by reading this.
Cheers!
